Abstract: A food product having on its surface at least one substance that reacts with a sanitizing compound to be applied to the food product is sanitized by applying an aqueous prewashing liquid to remove at least a portion of said substance and then applying an aqueous sanitizing liquid that contains ozone, each liquid being sprayed onto all exterior surfaces of the food product from a plurality of directions while moving the food product laterally with respect to the sprays, maintaining contact between said sanitizing liquid and said food product for at least a time effective to maximize wetting of the surface of the food product by the sanitizing liquid, and then removing mechanically at least 75% of the sanitizing liquid from said food product.

Abstract: The device forms snow from pressurized carbon dioxide fluids. A supply conduit delivers a flow of pressurized fluid. An expansion member attached to the supply conduit contains a plurality of channels for reducing pressure on the fluid and converting the fluid with reduced pressure into a mixed-phase stream of gas and fine snow particles. The channels have an average diameter and an average length of at least twice its average diameter. An agglomeration chamber attached to the plurality of channels agglomerates the fine snow particles by contacting the fine snow particles together.
